EL Inverter Whine

[Cloudschatze]

Any suggestions on how to silence an EL inverter? It's quite small in size, so I'm considering encapsulating it in high-temp hot glue. Does anyone have any experience doing this, or caution against?

I'm sure you mean, other than with a hammer?

I say gopher it.  You might want to figure out exactly which component is making the noise (prod the board with a chopstick or something) and then just glue that one. Or failing that, at least not encapsulating components that look like they want to emit heat (like the heatsinked one )

The whine is most probably caused by the inductor reel already highlighted in the picture. Since the whine usually comes from loose coils on the outside, a few dabs of hot glue across the coils should suffice. No need to completely cover it in gunk.

Thanks, guys.

The transformer is definitely the culprit here. I'll try just a few dabs of glue first, to see if that does the trick.

If it doesn't, perhaps I'll take up Tom's suggestion and "break it down" with MC Hammer.
